Fault 62 STO output

Fault: 62.1 (3E01hex | 15873dec)

Description: Short circuit at STO terminals

 

Response: FS – output fault

Cause

Measure

Short circuit between STO terminal and ground.

– Make sure that no external signals are connected to the STO terminals.

– Make sure that the STO terminals are not connected if the safety option is present (e.g. jumper plug must be removed).

Fault: 62.2 (3E02hex | 15874dec)

Description: Crossfault at STO terminals

 

Response: FS – output fault

Cause

Measure

Crossfault between an STO terminal and external voltage.

– Make sure that no external signals are connected to the STO terminals.

– Make sure that the STO terminals are not connected if the safety option is present (e.g. jumper plug must be removed).

Fault: 62.3 (3E03hex | 15875dec)

Description: STO circuit internal fault

 

Response: FS – output fault

Cause

Measure

Fault detected in STO circuit of device.

– Make sure that no external signals are connected to terminal X6 (STO).

– Make sure that terminal X6 (STO) is not connected (e.g. jumper plug must be removed).

– Switch the device off and on again.

– If the fault occurs repeatedly, replace the device and send it together with the fault number to SEW‑EURODRIVE. For further support, contact SEW‑EURODRIVE Service.

Fault: 62.4 (3E04hex | 15876dec)

Description: Extended diagnostics STO: test interval exceeded

 

Response: FS – warning

Cause

Measure

User fault: The parameter "Extended diagnostics STO" is set to "Test when deactivated and time monitoring". But no test has been performed within 8 hours.

– Activate and deactivate the STO drive safety function at least once within 8 hours.

– If time monitoring is not needed for the "Extended diagnostics STO" function, deactivate the function.

Fault: 62.5 (3E05hex | 15877dec)

Description: Excessive cyclic switching

 

Response: FS – output fault

Cause

Measure

Failed to complete diagnostics because of excessive cyclic switching.

– Check the application.

– Make sure that the STO safety sub-function is active or inactive at least once for 2.5 seconds within 60 seconds.

Fault: 62.6 (3E06hex | 15878dec)

Description: STO control internal fault

 

Response: FS – output fault

Cause

Measure

Fault detected on safety card by internal test of STO control.

If the fault occurs repeatedly, replace the device and send it together with the fault number to SEW-EURODRIVE. For further support, contact SEW‑EURODRIVE Service.

Fault: 62.7 (3E07hex | 15879dec)

Description: Undervoltage DC 24 V during diagnostics

 

Response: FS – output fault

Cause

Measure

Undervoltage of DC 24 V supply voltage detected during diagnostics.

– Check the DC 24 V supply voltage (permitted voltage range, voltage dips).

– If the fault occurs repeatedly, replace the device and send it together with the fault number to SEW-EURODRIVE, or replace the voltage supply. For further support, contact SEW‑EURODRIVE Service.

Fault: 62.93 (3E5Dhex | 15965dec)

Description: STO fault during external watchdog diagnostics

 

Response: FS – output fault

Cause

Measure

Fault detected in STO state during external watchdog diagnostics.

– Switch the device off and on again.

– Make sure that no external signals are connected to terminal X6 (STO).

– Make sure that terminal X6 (STO) is not connected (e.g. jumper plug must be removed).

– If the fault occurs repeatedly, replace the safety card and send it together with the fault number to SEW‑EURODRIVE. For further support, contact SEW‑EURODRIVE Service.
